Description

本発明は、吐出器に関する。   The present invention relates to a dispenser.

この種の吐出器として、従来、例えば下記特許文献１に示されているような、上方不正状態で押込み可能に起立したステムと、そのステムの上端部に装着された押下ヘッドと、押下ヘッドに被着された被覆体と、を備えた構成が知られている。上記した押下ヘッドには、ステムに連通する連通路を有するヘッド本体と、ヘッド本体の外周面から突出されていると共に前記連通路を介してステムに連通されたノズルと、が備えられている。被覆体は、上記した押下ヘッドを内側に収納する有頂筒状の部材であり、この被覆体の周壁部には、上記したノズルが挿通されるノズル開口が形成されている。このような吐出器によれば、被覆体によって押下ヘッドの装飾性を容易に向上させることができる。   Conventionally, as this type of dispenser, for example, as shown in Patent Document 1 below, a stem stood up so that it can be pushed in an upward improper state, a pressing head mounted on the upper end of the stem, and a pressing head A structure provided with a covered covering is known. The pressing head includes a head main body having a communication path communicating with the stem, and a nozzle protruding from the outer peripheral surface of the head main body and communicating with the stem via the communication path. The covering is a top-cylindrical member that houses the above-described pressing head inside, and a nozzle opening through which the above-described nozzle is inserted is formed in the peripheral wall portion of the covering. According to such a discharger, the decorativeness of the pressing head can be easily improved by the covering.

特開２００７−１６７８３２号公報（第５図）Japanese Patent Laying-Open No. 2007-167832 (FIG. 5)

しかしながら、上記した従来の吐出器では、外観が円柱形状の押下ヘッドに円筒形状の被覆体が装着されているため、押下ヘッドと被覆体とが相対的に軸線回りに回転可能となっている。したがって、被覆体と押下ヘッドとが相対的に軸線回りに回転しようとしたときに、ノズルがノズル開口に掛止され、ノズルに負荷がかかるおそれがある。   However, in the above-described conventional ejector, since the cylindrical covering body is mounted on the pressing head having a columnar appearance, the pressing head and the covering body can relatively rotate about the axis. Therefore, when the covering body and the pressing head are about to rotate about the axis, the nozzle is hooked on the nozzle opening, and a load may be applied to the nozzle.

また、仮に、ノズルが、ヘッド本体の外周面から突出されてなく、ノズル開口の径方向内側に対向配置されている場合には、被覆体と押下ヘッドとが相対的に軸線回りに回転して、ノズル開口とノズルとの周方向位置がずれてノズルが被覆体によって塞がれるという問題が生じる。   In addition, if the nozzle is not projected from the outer peripheral surface of the head main body and is opposed to the inner side in the radial direction of the nozzle opening, the cover and the pressing head rotate relatively around the axis. A problem arises in that the circumferential positions of the nozzle opening and the nozzle are shifted, and the nozzle is blocked by the covering.

本発明は、上記した従来の問題が考慮されたものであり、押下ヘッドと被覆体との軸線回りの相対的な回転を規制して被覆体のノズル開口によるノズルへの負荷を防止したり被覆体によるノズルの閉塞を防止したりすることができると共に、押下ヘッドに対する被覆体の周方向の位置決めを行って被覆体のノズル開口を押下ヘッドのノズル位置に容易に一致させることができる吐出器を提供することを目的としている。   In the present invention, the above-described conventional problems are considered, and the relative rotation around the axis of the pressing head and the covering body is regulated to prevent a load on the nozzle due to the nozzle opening of the covering body. A discharger capable of preventing the nozzle from being blocked by the body and positioning the covering body in the circumferential direction with respect to the pressing head to easily match the nozzle opening of the covering body with the nozzle position of the pressing head. It is intended to provide.

本発明に係る吐出器は、上方付勢状態で押込み可能に起立したステムと、該ステムの上端部に装着され、該ステムに連通するノズルが備えられた押下ヘッドと、該押下ヘッドに被着され、前記ノズルを外部に露出させるノズル開口が形成された被覆体と、を備える吐出器において、前記被覆体の下端部に切欠きが形成され、前記押下ヘッドの外周面に、前記切欠き内に配置された凸部が突設されていることを特徴としている。   A discharger according to the present invention includes a stem that is erected so as to be able to be pushed in an upward biased state, a pressing head that is attached to an upper end portion of the stem and includes a nozzle that communicates with the stem, and is attached to the pressing head. And a cover having a nozzle opening that exposes the nozzle to the outside, and a notch is formed in a lower end portion of the cover, and an inner surface of the notch The protrusion part arrange | positioned in is protrudingly provided.

このような特徴により、押下ヘッドの凸部が被覆体の切欠きの内縁に係止されることで、押下ヘッドと被覆体との相対的な軸線回りの回転が規制される。また、押下ヘッドに被覆体を被着させる際に、押下ヘッドの凸部を被覆体の切欠き内に配置させることで、押下ヘッドと被覆体との相対的な周方向の位置が決められる。   With such a feature, the convex portion of the pressing head is locked to the inner edge of the cutout of the covering body, so that the relative rotation between the pressing head and the covering body is restricted. Further, when the covering body is attached to the pressing head, the relative circumferential position of the pressing head and the covering body can be determined by arranging the convex portion of the pressing head within the cutout of the covering body.

また、本発明に係る吐出器は、前記被覆体が金属からなることが好ましい。
これにより、被覆体によって押下ヘッドが外観上、金属製となり、高級感を付与することが可能となる。 In the dispenser according to the present invention, the covering body is preferably made of a metal.
Thereby, the pressing head is made of metal in appearance by the covering, and it is possible to give a high-class feeling.

また、本発明に係る吐出器は、前記押下ヘッドの外周面及び前記被覆体の内周面のうちのいずれか一方に、軸方向に沿って延在する係合溝が形成され、他方に、前記係合溝の内側に配置される係合突起が突設されていることが好ましい。
これにより、係合突起が係合溝の内周面に係止されることで、押下ヘッドと被覆体との相対的な軸線回りの回転が規制される。また、押下ヘッドに被覆体を被着させる際、まず、押下ヘッドの上端部の外周に被覆体の下端部を被せる。このとき、係合突起を係合溝の内側に配置させる。次に、係合突起を係合溝に沿って摺動させながら被覆体を押下ヘッドに対して相対的に下降させる。これにより、被覆体の内側に押下ヘッドが収納されると共に、押下ヘッドの凸部が被覆体の切欠き内に配置される。このとき、係合溝が軸方向に沿って延在しているので、係合突起及び係合溝によって被覆体が軸方向に案内され、被覆体が軸方向に沿って下降し、被覆体の切欠き内に押下ヘッドの凸部が配置される。 Further, in the discharge device according to the present invention, an engagement groove extending along the axial direction is formed on one of the outer peripheral surface of the pressing head and the inner peripheral surface of the covering body, and on the other side, It is preferable that an engagement protrusion disposed inside the engagement groove is provided.
As a result, the engagement protrusion is locked to the inner peripheral surface of the engagement groove, thereby restricting the rotation of the pressing head and the cover around the relative axis. Further, when the covering body is attached to the pressing head, first, the lower end portion of the covering body is covered on the outer periphery of the upper end portion of the pressing head. At this time, the engaging protrusion is disposed inside the engaging groove. Next, the cover is lowered relative to the pressing head while sliding the engagement protrusion along the engagement groove. As a result, the pressing head is housed inside the covering, and the convex portion of the pressing head is disposed in the cutout of the covering. At this time, since the engaging groove extends along the axial direction, the covering body is guided in the axial direction by the engaging protrusion and the engaging groove, and the covering body descends along the axial direction. The convex part of the pressing head is arranged in the notch.

また、本発明に係る吐出器は、容器の口部に装着可能な装着キャップが備えられ、該装着キャップの天壁部には、軸方向に沿って延在すると共に平面視において内側に前記押下ヘッドが配置された立上り筒部が立設されており、該立上り筒部の内周面には、前記立上り筒部の上端に沿って周方向に延在する段差状の周溝部と、該周溝部から軸方向下側に向けて延在する縦溝部と、を備えた溝部が形成されており、該溝部の内側に前記凸部が移動可能に配置されていることが好ましい。   The discharge device according to the present invention is provided with a mounting cap that can be mounted on the mouth of the container, and the top wall of the mounting cap extends along the axial direction and is depressed inward in a plan view. A rising cylindrical portion on which the head is disposed is erected, and an inner peripheral surface of the rising cylindrical portion is provided with a step-shaped circumferential groove portion extending in a circumferential direction along an upper end of the rising cylindrical portion, It is preferable that the groove part provided with the longitudinal groove part extended toward the axial direction lower side from a groove part is formed, and the said convex part is arrange | positioned so that a movement is possible inside this groove part.

これにより、当該吐出器を使用しない時には、周溝部の内側のうち、縦溝部から周方向にずらした位置に凸部を配置させる。これにより、周溝部の下面に凸部が係止されるので、押下ヘッドの下降が規制される。一方、当該吐出器を使用する際には、まず、押下ヘッドを立上り筒部に対して相対的に軸線回りに回転させ、凸部を縦溝部の直上に配置させる。続いて、凸部を縦溝部に沿って移動させながら押下ヘッドを押し下げる。   Thereby, when not using the said discharge device, a convex part is arrange | positioned in the position shifted in the circumferential direction from the vertical groove part inside the circumferential groove part. Thereby, since a convex part is latched by the lower surface of a circumferential groove part, the fall of a pressing-down head is controlled. On the other hand, when using the discharger, first, the pressing head is rotated around the axis relative to the rising cylindrical portion, and the convex portion is arranged immediately above the vertical groove portion. Subsequently, the pressing head is pushed down while the convex portion is moved along the vertical groove portion.

本発明に係る吐出器によれば、押下ヘッドと被覆体との軸線回りの相対的な回転が規制されるので、被覆体のノズル開口によるノズルへの負荷を防止したり被覆体によるノズルの閉塞を防止したりすることができる。また、押下ヘッドに対する被覆体の周方向の位置決めを行って被覆体のノズル開口を押下ヘッドのノズル位置に容易に一致させることができる。   According to the ejector according to the present invention, since the relative rotation around the axis line between the pressing head and the covering body is restricted, the load on the nozzle due to the nozzle opening of the covering body is prevented or the nozzle is blocked by the covering body. Can be prevented. Further, the covering body can be positioned in the circumferential direction with respect to the pressing head so that the nozzle opening of the covering body can be easily matched with the nozzle position of the pressing head.

The pump 3 is attached to the attachment cap 2 by being fitted inside the part.

次に、押下ヘッド５のヘッド本体５０に被覆体６を被着させる工程を行う。
詳しく説明すると、図３に示すように、まず、ヘッド本体５０の上端側から被覆体６を被せて、被覆体６の下端部の内側にヘッド本体５０の上端部を挿入させる。このとき、被覆体６の係合突起６５をヘッド本体５０の係合溝５６の内側に配置させる。これにより、ヘッド本体５０の第一凸部５４の直上に被覆体６の第一切欠き６３が配置され、ヘッド本体５０の第二凸部５５の直上に被覆体６の第二切欠き６４が配置される。 Next, a step of attaching the covering 6 to the head main body 50 of the pressing head 5 is performed.
More specifically, as shown in FIG. 3, first, the covering body 6 is covered from the upper end side of the head body 50, and the upper end portion of the head body 50 is inserted inside the lower end portion of the covering body 6. At this time, the engagement protrusion 65 of the covering body 6 is disposed inside the engagement groove 56 of the head body 50. As a result, the first notch 63 of the cover 6 is disposed immediately above the first convex portion 54 of the head main body 50, and the second notch 64 of the cover 6 is directly above the second convex portion 55 of the head main body 50. Be placed.

続いて、被覆体６をヘッド本体５０に対して相対的に軸方向下側に移動させて被覆体６の内側にヘッド本体５０を嵌合させる。このとき、被覆体６の係合突起６５をヘッド本体５０の係合溝５６に沿って摺動させることで、被覆体６が軸方向に案内され、被覆体６は軸方向に沿って下降する。これにより、被覆体６の第一切欠き６３内にヘッド本体５０の第一凸部５４が嵌め込まれると共に、被覆体６の第二切欠き６４内にヘッド本体５０の第二凸部５５が嵌め込まれる。そして、これら切欠き６３，６４内に凸部５４，５５を配置させることで、ヘッド本体５０と被覆体６との相対的な軸線Ｏ回りの回転が規制される。これにより、ヘッド本体５０と被覆体６との相対的な周方向の位置決めが行われ、ノズル取付部５７の開口部５７ａと被覆体６のノズル開口６２とが合わせられ、ノズル取付部５７がノズル開口６２を介して外部に向けて開放される。   Subsequently, the cover body 6 is moved relatively downward in the axial direction relative to the head body 50, and the head body 50 is fitted inside the cover body 6. At this time, the covering body 6 is guided in the axial direction by sliding the engaging protrusion 65 of the covering body 6 along the engaging groove 56 of the head body 50, and the covering body 6 descends along the axial direction. . As a result, the first convex portion 54 of the head body 50 is fitted into the first notch 63 of the covering body 6 and the second convex portion 55 of the head body 50 is fitted into the second notch 64 of the covering body 6. It is. Then, by arranging the convex portions 54 and 55 in the notches 63 and 64, relative rotation of the head main body 50 and the cover 6 around the axis O is restricted. Thereby, the relative positioning of the head main body 50 and the covering body 6 is performed, the opening 57a of the nozzle mounting portion 57 and the nozzle opening 62 of the covering body 6 are aligned, and the nozzle mounting portion 57 is the nozzle. It opens toward the outside through the opening 62.

次に、ヘッド本体５０にノズル５１を取り付ける工程を行う。
詳しく説明すると、ノズル５１の基端部を被覆体６のノズル開口６２を通してヘッド本体５０のノズル取付部５７の内側に挿入し、ノズル５１の係合凸部５８によってノズル５１の基端部をノズル取付部５７の内側に嵌合させる。これにより、ノズル５１の内側とヘッド本体５０の図示せぬ連通路が連通される。 Next, a process of attaching the nozzle 51 to the head body 50 is performed.
More specifically, the base end portion of the nozzle 51 is inserted into the inside of the nozzle mounting portion 57 of the head body 50 through the nozzle opening 62 of the covering body 6, and the base end portion of the nozzle 51 is inserted into the nozzle by the engagement convex portion 58 of the nozzle 51. The fitting part 57 is fitted inside. Thereby, the inside of the nozzle 51 and the communication path (not shown) of the head main body 50 are communicated.

次に、ヘッド本体５０をステム４の上端部に装着させる工程を行う。
詳しく説明すると、ヘッド本体５０をステム４の上端部に嵌合させ、ヘッド本体５０の図示せぬ連通路とステム４の内側とを連通させる。このとき、ヘッド本体５０の第一凸部５４を装着キャップ２の立上り筒部２２の第一溝部２４の内側に配置させると共に、ヘッド本体５０の第二凸部５５を立上り筒部２２の第二溝部２５の内側に配置させる。上記した第一凸部５４と第二凸部５５、及び、第一溝部２４と第二溝部２５は、それぞれ外観形状（大きさ）が異なっているので、それぞれを目視で容易に確認することが可能である。そして、第一凸部５４を第一溝部２４の内側に、第二凸部５５を第二溝部２５の内側に配置させることで、押下ヘッド５の装着キャップ２に対する相対的な周方向位置が決められ、ノズル５１が所定の向きに配置される。 Next, a process of attaching the head main body 50 to the upper end portion of the stem 4 is performed.
More specifically, the head main body 50 is fitted to the upper end portion of the stem 4, and a communication path (not shown) of the head main body 50 and the inside of the stem 4 are communicated. At this time, the first convex portion 54 of the head main body 50 is disposed inside the first groove portion 24 of the rising cylindrical portion 22 of the mounting cap 2, and the second convex portion 55 of the head main body 50 is disposed in the second portion of the rising cylindrical portion 22. It arrange | positions inside the groove part 25. FIG. Since the above-described first convex portion 54 and the second convex portion 55, and the first groove portion 24 and the second groove portion 25 have different external shapes (sizes), they can be easily confirmed visually. Is possible. Then, the relative circumferential direction position of the pressing head 5 with respect to the mounting cap 2 is determined by arranging the first convex portion 54 inside the first groove portion 24 and the second convex portion 55 inside the second groove portion 25. The nozzle 51 is arranged in a predetermined direction.

以上により、吐出器１の組み立てが完了する。なお、ヘッド本体５０に被覆体６を被着させる前、又は、ヘッド本体５０にノズル５１を取り付ける前に、ヘッド本体５０をステム４の上端部に装着させてもよい。   Thus, the assembly of the discharger 1 is completed. Note that the head body 50 may be attached to the upper end portion of the stem 4 before the covering body 6 is attached to the head body 50 or before the nozzle 51 is attached to the head body 50.

次に、上記した吐出器１の使用方法について説明する。   Next, the usage method of the above-mentioned discharger 1 is demonstrated.

まず、吐出器１を使用しない時には、周溝部２６，２８の内側のうち、縦溝部２７，２９から周方向にずれた位置に凸部５４，５５を配置させる。具体的には、図２の二点鎖線で示すように、第一周溝部２６の他端部（周方向における第一縦溝部２７側の反対側）に第一凸部５４を配置すると共に、第二周溝部２８の他端部（周方向における第二縦溝部２９側の反対側）に第二凸部５５を配置する。これにより、第一周溝部２６の下面２６ａに第一凸部５４が掛止されると共に、第二周溝部２８の下面２８ａに第二凸部５５が掛止されるので、押下ヘッド５の下降が規制される。   First, when the dispenser 1 is not used, the convex portions 54 and 55 are arranged at positions shifted in the circumferential direction from the longitudinal groove portions 27 and 29 inside the circumferential groove portions 26 and 28. Specifically, as shown by a two-dot chain line in FIG. 2, the first convex portion 54 is disposed on the other end portion of the first circumferential groove portion 26 (the side opposite to the first vertical groove portion 27 side in the circumferential direction), and The second convex portion 55 is disposed on the other end portion of the second circumferential groove portion 28 (the side opposite to the second vertical groove portion 29 side in the circumferential direction). Accordingly, the first convex portion 54 is hooked on the lower surface 26a of the first circumferential groove portion 26, and the second convex portion 55 is hooked on the lower surface 28a of the second circumferential groove portion 28. Is regulated.

一方、吐出器１を使用する際には、まず、図２の実線で示すように、押下ヘッド５を立上り筒部２２に対して相対的に軸線Ｏ回りの一方側に回転させ、凸部５４，５５を縦溝部２７，２９の直上に配置させる。具体的に説明すると、押下ヘッド５と立上り筒部２２とを相対的に軸線Ｏ回りに回転させ、第一凸部５４を第一周溝部２６の他端部から一端部側に移動させて第一周溝部２６の下面２６ａから外すと共に、第二凸部５５を第二周溝部２８の他端部から一端部側に移動させて第二周溝部２８の下面２８ａから外す。   On the other hand, when using the discharger 1, first, as shown by the solid line in FIG. 2, the pressing head 5 is rotated relative to the rising cylindrical portion 22 to one side around the axis O, and the convex portion 54. , 55 are arranged immediately above the longitudinal groove portions 27, 29. More specifically, the pressing head 5 and the rising cylindrical portion 22 are relatively rotated around the axis O, and the first convex portion 54 is moved from the other end portion of the first circumferential groove portion 26 to the one end portion side. While removing from the lower surface 26a of the 1st circumferential groove part 26, the 2nd convex part 55 is moved to the one end part side from the other end part of the 2nd circumferential groove part 28, and is removed from the lower surface 28a of the 2nd circumferential groove part 28.

続いて、凸部５４，５５を縦溝部２７，２９に沿って移動させながら押下ヘッド５を押し下げる。詳しく説明すると、押下ヘッド５に被着された被覆体６の天壁部６０の上面を指等で押圧し、押下ヘッド５を押し下げる。このとき、第一凸部５４が、軸方向に延在する第一縦溝部２７内に配置されていると共に、第二凸部５５が、軸方向に延在する第二縦溝部２９内に配置されるので、これら凸部５４，５５及び縦溝部２７，２９によって押下ヘッド５が軸方向に沿って案内される。これにより、押下ヘッド５が回転しないで軸方向に沿って真直ぐに押し下げられる。   Subsequently, the pressing head 5 is pushed down while the convex portions 54 and 55 are moved along the vertical groove portions 27 and 29. More specifically, the upper surface of the top wall 60 of the covering 6 attached to the pressing head 5 is pressed with a finger or the like, and the pressing head 5 is pressed down. At this time, the first convex portion 54 is disposed in the first vertical groove portion 27 extending in the axial direction, and the second convex portion 55 is disposed in the second vertical groove portion 29 extending in the axial direction. Therefore, the pressing head 5 is guided along the axial direction by the convex portions 54 and 55 and the vertical groove portions 27 and 29. Thereby, the pressing head 5 is pushed down straight along the axial direction without rotating.

上述したように押下ヘッド５が押し下げられると、押下ヘッド５に嵌着されたステム４がシリンダ３０内に押し込められ、ステム４と共にポンプ３の図示せぬピストンが下降する。これにより、シリンダ３０内の内容物がステム４内を通ってヘッド本体５０の図示せぬ連通路内に流入し、その連通路内からノズル５１内に流入してノズル５１の先端から外部に吐出される。   When the pressing head 5 is pushed down as described above, the stem 4 fitted to the pressing head 5 is pushed into the cylinder 30 and the piston (not shown) of the pump 3 is lowered together with the stem 4. As a result, the contents in the cylinder 30 pass through the stem 4 and flow into a communication path (not shown) of the head main body 50, flow into the nozzle 51 from the communication path, and discharge from the tip of the nozzle 51 to the outside. Is done.

続いて、上記した押下ヘッド５の押し下げを解除すると、ポンプ３の図示せぬ付勢部材によって図示せぬピストンが上昇し、このピストンに連結されたステム４及び押下ヘッド５がそれぞれ押し上げられ、押下ヘッド５が元の位置に戻される。これにより、ノズル５１からの内容物の吐出が停止すると共に、容器１０内の内容物がディップチューブ７を通ってシリンダ３０内に供給される。   Subsequently, when the pressing down of the pressing head 5 is released, a piston (not shown) is lifted by a biasing member (not shown) of the pump 3, and the stem 4 and the pressing head 5 connected to the piston are respectively pushed up and pressed. The head 5 is returned to the original position. Thereby, the discharge of the content from the nozzle 51 is stopped, and the content in the container 10 is supplied into the cylinder 30 through the dip tube 7.

そして、吐出器１の使用後は、押下ヘッド５を立上り筒部２２に対して相対的に軸線Ｏ回りの他方側に回転させ、凸部５４，５５を周溝部２６，２８の下面２６ａ，２８ａ上に配置させる。周溝部２６，２８の下面２６ａ，２８ａに凸部５４，５５が掛止され、押下ヘッド５の下降が規制される。   After the use of the ejector 1, the pressing head 5 is rotated relative to the rising cylindrical portion 22 to the other side around the axis O, and the convex portions 54 and 55 are moved to the lower surfaces 26 a and 28 a of the circumferential groove portions 26 and 28. Place on top. The convex portions 54 and 55 are hooked on the lower surfaces 26a and 28a of the circumferential groove portions 26 and 28, and the lowering of the pressing head 5 is restricted.

上記した構成からなる吐出器１によれば、押下ヘッド５の凸部５４，５５が被覆体６の切欠き６３，６４の内縁に係止されることで、押下ヘッド５と被覆体６との相対的な軸線Ｏ回りの回転が規制されている。したがって、被覆体６のノズル開口６２の縁部によってノズル５１の外周面が押圧されず、ノズル開口６２によるノズル５１への負荷を防止することができる。   According to the dispenser 1 having the above-described configuration, the convex portions 54 and 55 of the pressing head 5 are locked to the inner edges of the notches 63 and 64 of the covering body 6, so that the pressing head 5 and the covering body 6 The rotation around the relative axis O is restricted. Therefore, the outer peripheral surface of the nozzle 51 is not pressed by the edge of the nozzle opening 62 of the covering 6, and a load on the nozzle 51 by the nozzle opening 62 can be prevented.

また、切欠き６３，６４内に凸部５４，５５を配置させることで、ヘッド本体５０と被覆体６との相対的な軸線Ｏ回りの回転が規制され、ヘッド本体５０と被覆体６との相対的な周方向の位置が決められるので、ノズル取付部５７の開口部５７ａと被覆体６のノズル開口６２との位置を一致させることができる。これにより、ノズル取付部５７とノズル開口６２との周方向位置を合わせる作業を省略することができ、吐出器１の生産性を向上させることができる。   Further, by arranging the convex portions 54 and 55 in the notches 63 and 64, the rotation of the head main body 50 and the covering body 6 around the relative axis O is restricted, and the head main body 50 and the covering body 6 are prevented from rotating. Since the relative circumferential position is determined, the positions of the opening 57a of the nozzle mounting portion 57 and the nozzle opening 62 of the covering 6 can be matched. Thereby, the operation | work which aligns the circumferential direction position of the nozzle attachment part 57 and the nozzle opening 62 can be skipped, and the productivity of the discharge device 1 can be improved.

また、被覆体６が金属からなるため、被覆体６によって吐出器１における押下部分が外観上、金属製となる。これにより、吐出器１の装飾性を向上させることができる。   In addition, since the covering 6 is made of metal, the pressed portion of the discharger 1 is made of metal in appearance by the covering 6. Thereby, the decorativeness of the discharger 1 can be improved.
